Product Overview
An outboard with no spark on both cylinders, intermittent shutdown when hot, or an ignition signal that fails specification may need a CDI module. Before replacement, test the stop circuit, stator, trigger, grounds, coils, connectors, and cranking speed because the module is often blamed for faults upstream.
The CDI stores and switches ignition energy at the correct timing signal. It cannot restore spark if the charge coil or trigger does not supply the required output.
Order by exact engine model, year, cylinder count, connector colors, mounting pattern, and original module number. Horsepower alone is not enough.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application that is not shown above. Model year, production date, serial number, engine or equipment specification, installed options, and previous repairs can change fitment. Match the original part, reference number, dimensions, connectors, mounting points, and product photos before purchase.
Frequently Asked Questions
Q: Can a bad CDI cause no spark? A: Yes, but stator, trigger, stop circuit, grounds, coils, and wiring should be tested first.
Q: Does it fit every Yamaha 25 HP? A: No. Model, year, cylinder count, module number, and connectors must match.
Q: Can I return-test a CDI with a normal ohmmeter? A: Static resistance alone may not prove the module. Follow the ignition diagnostic procedure and peak-voltage specifications.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
